A distribution board (known in the United States as a (circuit) breaker panel, panelboard, or load center or for old ones, fuse box) is a mounting enclosure for multiple electrical circuit breakers. These are generally placed in two columns. Small single-phase boxes, with the breakers in just one row, are known as consumer units in Britain. Distribution boards are typically found in central locations inside buildings and often serve as the point at which electricity is distributed within a building. Circuit breakers can be used to manually de-energize electrical circuits when the downstream wiring is being serviced. DIN-RAIL Power Supplies.

Circuit breaker panels are always dead front, that is, the operator of the circuit breakers cannot contact live electrical parts. During servicing of the distribution board itself, though, when the cover has been removed and the cables are visible, North American breaker panels commonly have some live parts exposed. British distribution boards generally have the live parts enclosed to IP20, even when the cover has been removed for servicing.

Breaker arrangement

Breakers are usually arranged in two columns. In a US-style board, breaker positions are numbered left-to-right, along each row from top to bottom. Power supplies - din rail by Sola/Hevi-Duty Power Supply / Din Rail Power Supplies.
